Take an Istanbul sightseeing tour with a difference: one that visits the beautiful Süleymaniye Mosque instead of the Blue Mosque, plus three other iconic sights. With a knowledgeable guide, absorb the calm beauty of the Süleymaniye, Istanbul’s largest mosque, which was built for Süleyman I in the 16th century. Plus, visit the underground Basilica Cistern, explore the Grand Bazaar, and marvel at the treasures, courtyards and harem of the Topkapi Palace, once home to Ottoman sultans. Your full-day tour includes a tasty 3-course Turkish lunch at a hotel midway through.
